Summary:
- The James Webb Space Telescope (JWST) has a new instrument called the Near-Infrared Imager and Slitless Spectrograph (NIRISS) that can sharpen its vision and allow it to see faint, distant galaxies more clearly.
- The NIRISS instrument uses a technique called interferometry to combine light from different parts of the telescope's mirror, which helps to reduce blurring and improve the telescope's resolution.
- This enhancement to the JWST's capabilities will enable it to study the early universe in greater detail, providing insights into the formation and evolution of galaxies in the first few hundred million years after the Big Bang.
